SPECIFICATION forming part Of Letters Patent N0. 716,085, dated December 16, 1902- Appleationriiled November 21, 1901. Serial No. 83,146. (No model.)

To all whom t may concern.'

Be it known that I, WILLIAM H. NELSON, a

citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Nut- Locks, of which` the following is a specification.

This invention relates to nut-locks, and has special reference to that type of locks de'- Io signed for securely fastening the nuts of a plurality of bolts.

The present invention relates to that class of such devices comprising a thin bar having a plurality of bendable tongues to be bent to I5 embrace the sides of the nuts and openings for the passageof the bolts.

The novelty in the present instance resides in the peculiar construction and adaptation of parts, all as more fully hereinafter dezo scribed, shown in the drawings, and then par-` ticularly pointed out in the claim.

In the drawings, Figure l is a perspective view of a rail-joint fitted with the improved nut-lock constructed in accordance with the present invention. Fig. 2 is a perspective view of the nut-lock, showing in dotted lines i -the nuts and illustrating the different ways in which the fastening-tongues maybe employed.

3o blank, illustrating the preferable construction thereof.

Like numerals of reference designate corresponding parts in the several flgures'of the drawings.

5 5 In the preferable construction, as shown in able fastening-tongues 3,' which are of `a sufficient length to bend up a material distance over or against a side of the nut to firmly brace the same against turning. In the construction illustrated it is found to be of ad- 5o vantage to employ a plurality of the laterally- Fig. 3 is a plan view of the nut-lock" projecting fastening-tongues 3, inasmuch as while ordinarily Vone of'such tongues is sufiicient to constitute a lock for the nut, still in the event of such tongue becoming broken another may be brought into action, thus retaining the efficiency of the lock and greatly prolonging its durability.

The laterally-projecting bendable fastenl ing-tongues 3 of the individual washers 2 may radiate from the body of the Washer in direc- 6o tions best suited for the particular kind of work; but ordinarily there are a pair of diametrically opposite tongues 3, which, if desired, can be brought up against opposite sides of the nut by the means of claW-pincers or like tools, as indicated in Fig. 2 of the drawings.

Each of the individual Washers 2 is provided with a central bolt-opening 4, through which the bolt projects, and therefore per- 7o mits of the nut-lock being readily slipped over the bolt ends before the nuts are secured into position upon the faces of the Washers. Itis therefore obvious that the lock as an entirety may be quickly placed in position and the tongue or tongues 3 also quickly bent up against the sidesof the nuts after being screwed tight by any convenient form of tool.

.This is a great advantage in railway con- .of the rail and lies wholly at one side of the plane of the bolts and nuts, thereby constituting not only a coupling between the several individual washers, but also a rigid brace which positively prevents any independent 9o movement of the individual washers. In effect all of the nuts with which the lockis associated may be said to be locked together by common means. The said advantageous results would attend the use of the nut-lock in bridgework and other places. l

From the foregoing it is thought that the construction and use of the herein-described lock will be readily apparent Without further description.

IOO

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improved article of manufacture, the nut-lock herein described consisting of a continuous locking-bar of thin metal having offset from one side thereof at the ends and intermediate thereof, independent like washers each integral with the bar and of suflicient area to constitute a complete washer in itself, each of said washers formed with a plurality of lateral projecting bendable fasteningtongues, each washer being provided with a centrally-disposed opening and the tongues being of less width than the sides of the 0E- set portion from which they extend, said tongues being in the plane of the bar with the outer end tongues projecting beyond the ends of the bar proper, the main longitudinal portion of the bar adapted to extend beneath zo the nuts and the bendable tongues to be engaged over one or more of the other sides thereof, all substantially as herein shown and described.

In testimony whereof I affix my signature z 5
